This month we have added a Flash version of the PowerPoint files. Files created with the newer versions of PowerPoint may have features, especially animations, that don't work in the older versions. To help you have access to the files with all of their intended features, we have converted them to Flash files and listed them with the PowerPoint versions. Over 90% of the computers in use in the US today have the Flash player installed.
If the PowerPoint file doesn't work, you may have an older version of PowerPoint. Try downloading the Flash file as an alternative. As an added benefit, the
flash versions are usually smaller files and take less time to download.
If you download the Flash version, look near the bottom right corner for an icon that will expand the presentation so that it fills your whole screen. Use the controls at the bottom left to stop and start the presentation. Click a slide to move on if it doesn't move when you want it to move.
